Benefits of technology

The patent text describes an energy storage system that uses a solid electrolyte, which eliminates liquid electrolytes that may leak or release gas. The solid state energy system is maintenance-free, resistant to temperature changes, and less flammable. This makes it ideal for portable devices like consumer goods. Additionally, the high heat resistance allows for standard processing steps to be performed without damaging the energy storage system. The energy storage system can withstand temperatures of up to 260° without damage, which makes it compatible with external circuit environments during reflow processes.

Problems solved by technology

Since their constituents may consist of thin layers, the overall height of such an energy storage system may be extremely small.

Embodiment Construction

[0042]FIG. 1 shows an energy storage system ES with a first electrode EL1 in a first electrode layer and a second electrode EL2 in a second electrode layer. Between the first electrode EL1 and the second electrode EL2 an electrolyte E is arranged in an electrolyte layer.

[0043]The electrolyte E separates the two electrodes EL1, EL2 spatially from one another and is preferably ion-conductive. A voltage may be tapped at the two electrodes EL1, EL2 which may, for example, be used to operate an electrical device.

[0044]The voltage between the electrodes EL1, EL2 depends on the choice of materials. The materials may be selected such that a maximum voltage does not necessarily drop at the layer stack but rather a maximum energy density may be stored in the layer stack or a maximum current intensity may be retrieved from the layer stack.

[0045]A first active layer AL1 may be arranged between the first electrode EL1 and the electrolyte E. A second active layer AL2 may be arranged between the e...

Abstract

An energy storage system is disclosed. In an embodiment, an energy storage system includes a layer stack with a first electrode layer, a second electrode layer and an electrolyte layer between the first and second electrode layers, a first electrode located in the first electrode layer, a second electrode located in the second electrode layer and an electrolyte formed in the electrolyte layer, wherein the electrolyte is a solid.

Description

[0001]This patent application is a national phase filing under section 371 of PCT / EP2018 / 063679, filed May 24, 2018, which claims the priority of German patent application 102017111972.8, filed May 31, 2017, each of which is incorporated herein by reference in its entirety.TECHNICAL FIELD[0002]The invention relates to energy storage systems, e.g., for electrical devices, with small dimensions and high energy density.BACKGROUND[0003]Energy storage systems in electrical devices serve to supply electrical circuits with electrical energy independently of an external power supply.[0004]Conventional portable electrical devices may, for example, be battery-powered or storage battery-powered. Capacitors are available for short-term energy supply.[0005]A problem with known energy storage systems is, for example, the low energy density thereof.SUMMARY OF THE INVENTION[0006]Embodiments provide an improved energy storage systems.[0007]Various embodiments provide an energy storage system compris...
